Technology

At Bitzi, files were identified by applying a strong

]

Bitzi cross-referenced multiple Uniform Resource Identifiers (URIs) for files, primarily URIs used by peer-to-peer file-sharing networks and/or clients:

• sha1:/magnet: (Gnutella
  )
• kzhash: (Grokster)
• tree:tiger: (DC++, Shareaza).
• OverNet
  )

Other file-specific metadata was also collected, such as

details, user ratings, and free-form comments or descriptions. Users could displace flawed information with new contributions.

Data about specific files can also be programmatically retrieved via a

Relationship to peer-to-peer networks

Bitzi originated several popular standards in the peer-to-peer file sharing sphere, including the Magnet URI scheme and Tiger tree hashes.

Many peer-to-peer file sharing programs, including

versions, offered an option to look up local files or network search results at Bitzi for more information about their contents or quality.

As peer-to-peer file sharing networks often have mislabeled or corrupt files, Bitzi can sometimes provide additional confidence that a file is as expected, before a user begins a long download. In such a role, Bitzi served to ameliorate some common attacks on peer-to-peer networks.
